and the transaction was fair. With the increase of coke price, the cost of ductile iron in Shanxi, Henan, Liaoning, Shandong and other regions has increased. In addition, with the gradual release of downstream demand, the inventory of iron plants is not large, and iron plants have successively raised their prices. There are few iron foundries in Shandong, Jiangsu, Hebei and Shanxi and the inventory remains low. As the coke price rises and the cost increases, the price of iron foundries rises again.Tangshan billets rose sharply last weekend,Brunswick15CrMo alloy steel plate, steel mills in some northern cities implemented production restriction, and some domestic economic data improved, which boosted manufacturers confidence. Today, steel prices generally rose. However, with the approaching meeting and the rainfall in the south caused by the typhoon, the construction progress of the downstream construction site is affected, which is not conducive to the continuous demand. The high spot price transaction today is weak, which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow, and some businesses may reduce prices and take goods.Brunswick,Reasons for copper pipe corrosion: Air pollution.Although the opening continued the weak trend, the intraday transactions improved, and the prices of some copper bar manufacturers rose. From the specific situation although the manufacturer feedback that the shipment is average, the mentality is relatively calm, the market inventory is not much, and the manufacturer is not willing to significantly reduce the price. In terms of the market, the transaction of strip steel is better than other steel varieties, and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake, the overall demand for strip steel remains in a good state.Bergamo,BrunswickBronze plate,The blowpipe shall be perpendicular to the lead pipe during welding, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.First of all, we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C, while the humidity should be normal. The room should be kept ventilated.Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.

The second of the five application fields of red copper plate T, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, brewing pots, etc.How to make copper tubes shine copper is stable in dry air, but the surface of power copper tubes is easy to be corroded in humid air, generating a layer of green material, commonly known as & quot; copper green& quot;, how to remove verdigris? We can remove the verdigris by mechanical friction, but this is not only troublesome, but also will damage the surface of the bronze. Here s a good way to remove verdigris. Use a measuring cylinder to measure ml of concentrated ammonia water and put it into a beaker, then add ml of distilled water, stir it with a glass rod to prepare ammonia solution, that is, wipe copper water. Copper rubbing water can react with verdigris to form soluble blue copper ammonia complex, thus removing the verdigris. In order to improve the effect of removing verdigris from the copper polishing water, chalk or talcum powder can also be mixed into the copper polishing water, which can increase the mechanical friction, fully expose the deep layer of copper rust, ensure the complete reaction of verdigris and ammonia, and make the copper surface smooth and bright. Dip cotton in copper water and repeatedly scrub copper products with copper rust. Soon, the copper rust disappeared from the surface of the bronze ware, and the copper products showed a bright metallic luster again, while the cotton was dyed blue. When the verdigris on some copper products are not easy to remove, soak them in the copper scrubbing water for a while, and then scrub them with cotton dipped in the copper scrubbing water.At the opening this morning the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform, the current market price of * mm Linyi copper bar was yuan (ton price, the same below), the * mm copper bar was yuan, and the * mm copper bar Henan copper bar was yuan.Honesty and mutual benefit,Five of the five major application fields of copper plate, copper bar and copper tube: copper is used in medicine. In the s, Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s, and successfully developed the corresponding & quot; Cancer Suppressing & quot;, which is successful in the near future.Some steel mills in Liaoning are interested in purchasing pig iron, but the local resources are tight, and the iron mills quotations are on the high side resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei, Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases, the quotation of iron mills continues to decline. At present, the demand and cost support are weak, and there is no positive boost. The short-term pig iron market is weak and difficult to change.When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.

Generally, oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.Direct material,I don t know how to keep the copper tube.To prevent the copper pipe surface the humidity of the packaging materials should be well controlled, and the moisture content of all wood and paper packaging materials should be strictly controlled below %. Each plate of material is tightly packed with PE film to avoid the copper pipe absorbing moisture from the outside.The second of the five application fields of red copper plate T, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, etc.Brunswick,When stacking, it shall be stacked reasonably and placed first.Disadvantages: Due to loose tissue and high pressure resistance, the pipe is only used to produce small air conditioning copper rods.Red copper inventory in key areas has risen continuously, but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wu an, Jiangyin and Lecong,BrunswickBronze tube, the inventory level remains relatively moderate and the pressure on the market is relatively small. In Wu an market, according to the data, increasing by tons on a weekly basis. In late April, it reached tons lower in the year, down tons from the high level after the Spring Festival, and rose for three consecutive weeks. In terms of the ovquantity
